[0044] 为了传输,基带处理器34从控制系统32接收表示语音、数据或控制信息的数字化数据,它进行编码以便传输。 [0044] For transmission, the baseband processor 34 receives from the control system 32 represent voice, data, or control information in the digital data, it is encoded for transmission. 编码数据被输出到发射电路36,其中,它被调制器用来调制在一个或多个期望的发射频率上的载波信号。 The encoded data is output to the transmit circuitry 36, where it is used to modulate a carrier signal is modulated on one or more desired transmit frequency or frequencies. 功率放大器(未示出)将把已调载的载波信号放大到一个适合于传输的水平,并且经由一个匹配网络(未示出)把被调制的载波信号递送到天线40。 A power amplifier (not shown) will amplify the modulated carrier carrier signal to a level appropriate for transmission, and via a matching network (not shown) to deliver the modulated carrier signal to the antenna 40. 本领域技术人员可用的不同调制和处理技术被用于在移动终端和基站之间的信号传输。 Those skilled in the art available to different modulation and processing techniques are used for signal transmission between the mobile terminal and the base station.

[0045] 在0FDM调制中,传输频带被划分成多个正交载波。 [0045] In 0FDM modulation, the transmission band is divided into multiple orthogonal carriers. 每个载波都根据将被发射的数字数据来调制。 Each carrier is modulated according to the digital data to be transmitted. 因为0FDM把传输频带划分成多个载波,所以每载波的带宽减少并且每载波的调制时间增加。 0FDM because the transmission band into multiple carriers, the bandwidth per carrier decreases and the modulation time per carrier increases. 因为多个载波被并行发射,所以在任何给定载波上的数字数据或码元的传输速率低于使用单个载波的时候。 Since the multiple carriers are transmitted in parallel, so that the digital data on any given carrier or symbol transmission rate lower than when using a single carrier.

[0046] 0FDM调制对要被发射的信息利用快速傅里叶逆变换(IFFT)的特性。 [0046] 0FDM the modulation characteristic information to be transmitted using the inverse fast Fourier transform (IFFT) a. 为了解调, 被接收信号上的快速傅里叶变换(FFT)特性恢复被发射的信息。 For demodulation, a Fast Fourier Transform (FFT) on the received signal characteristics of the transmitted information is restored. 实际上,IFFT和FFT分别通过实现离散傅里叶逆变换(IDFT)和离散傅里叶变换(DFT)的数字信号处理来提供。 Indeed, IFFT and FFT are provided by Inverse Discrete Fourier Transform (IDFT) and Discrete Fourier Transform digital signal processing (DFT) of. 因此,0EDM调制的表征特色是正交载波被生成用于传输信道内的多个频带。 Accordingly, the characterizing features 0EDM modulated orthogonal carriers are generated for multiple bands within a transmission channel. 已调制信号是具有相对低传输速率并且能够稳定在它们的相应频带内的数字信号。 Modulated signal having a relatively low transmission rate and capable of stably within their respective bands of the digital signal. 独立载波不通过数字信号直接调制。 Individual carriers are not modulated directly by the digital signals. 替代地,所有载波都通过IFFT处理被立即调制。 Instead, all carrier waves are modulated by IFFT processing immediately.

[0047] 在操作中,0FDM被优选地至少用于从基站14到移动终端16的下行链路传输。 [0047] In operation, 0FDM is preferably used for at least downlink transmission from the base station 14 to the mobile terminal 16. 每个基站14都配备有"n"个发射天线28,并且每个移动终端16都配备有"m"个接收天线40。 Each base station 14 is equipped with "n" transmit antennas 28, 16 and each of the mobile terminals are equipped with "m" receive antennas 40. 特别地,各天线可以用适当双工器或交换机被用于接收和发射,并且因此仅仅为了清楚起见而被标记。 In particular, each antenna duplexer or may be a suitable switch is for receiving and transmitting, and thus only be labeled for clarity.

[0048] 参考图4,逻辑0FDM发射结构将被描述。 [0048] Referring to FIG 4, the logical structure 0FDM emission will be described. 开始,基站控制器10将要被发射到不同移动终端16的数据发送到基站14。 Starts, the base station controller 10 to be transmitted to various mobile terminals 16 to transmit data to the base station 14. 基站14可以使用与移动终端相关联的信道质量指示符(CQI)为发射调度数据以及为发射被调度的数据选择适当的编码和调制。 The base station 14 may use the mobile terminal associated with the channel quality indicator (CQI) and the data transmission schedule to select the appropriate coding and modulation to transmit scheduled data. 基于移动终端16 提供的信息,CQI可以直接来自移动终端16或者在基站14上被确定。 Based on the information provided by the mobile terminal 16, CQI may be directly from the mobile terminals 16 or determined at the base station 14. 在任一情况中,每个移动终端16的CQI都是信道振幅(或响应)在0FDM频带中变化程度的函数。 In either case, the CQI for each mobile terminal 16 is a function of the degree of change of channel amplitude (or response) in 0FDM band.

[0049] 通过用数据扰码逻辑46来降低与数据相关联的峰值平均功率比的方法,调度数据44(该调度数据44是比特流)被扰码。 [0049] by the method of data scrambling logic 46 associated with the data to reduce the peak to average power ratio, scheduling data 44 (the scheduled data of the bitstream 44) are scrambled. 用于扰码数据的循环冗余校验(CRC)被确定并且使用CRC添加逻辑48被附加到扰码数据。 Scrambling data used for cyclic redundancy check (CRC) is determined using CRC adding logic 48 is attached to the scrambled data. 接下来,信道编码用信道编码器逻辑50被执行来有效地向数据添加冗余,以便在移动终端16上易于恢复和纠错。 Next, channel coding with the channel encoder logic 50 is performed to effectively add redundancy to the data, in order to facilitate recovery and error correction at the mobile terminal 16. 再一次,用于特殊移动终端16的信道编码是基于CQI。 Again, the channel coding for a particular mobile terminal 16 is based on the CQI. 在某些实施中,信道编码器逻辑50使用已知的Turbo编码技术。 In certain embodiments, the channel encoder logic 50 uses known Turbo encoding techniques. 然后,编码数据被速率匹配逻辑52处理来补偿与编码相关联的数据扩展。 Then, the encoded data is data matching logic 52 to compensate for expansion associated with encoding rate.

[0050] 比特交织器逻辑54系统地重新排序编码数据中的比特以便最小化连续数据比特的损失。 [0050] Bit interleaver logic 54 systematically reorders the bits in the encoded data to minimize the loss of consecutive data bits. 取决于所选择的基带调制,通过映射逻辑56将得到的数据比特系统地映射成对应的码元。 Depending on the chosen baseband modulation, bits are systematically mapped into corresponding symbols by mapping logic 56. The data obtained. 优选地,正交调幅(QAM)或四相移键控(QPSK)调制被使用。 Preferably, quadrature amplitude modulation (QAM) or quadrature phase shift keying (QPSK) modulation is used. 调制度优选地基于特殊移动终端的CQI来选择。 Preferably the modulation based on the CQI to select a specific mobile terminal. 码元可以被系统地重新排序来用码元交织器逻辑58进一步加固传输信号对频率选择性衰落引起的定期数据损失的抗扰。 Symbols may be systematically reordered to further reinforcement of the transmission signal 58 regular data loss caused by frequency selective fading using symbol interleaver immunity logic.

[0051] 此时,比特群已经被映射成表示振幅位置和相位星座的码元。 [0051] At this time, the group of bits have been mapped into symbols represents constellation amplitude and phase position. 当空间分集被期望时,码元块然后被时空块码(STC)编码器逻辑60处理,其用使传输信号对干扰更有抵抗力并且更容易在移动终端16被解码的方式来修改码元。 When spatial diversity is desired, blocks of symbols are then space-time block code (STC) encoder logic 60, so that the transmission signal which was more resistant to interference and more readily decoded at a mobile terminal 16 in a manner to modify the symbol . STC编码器逻辑60将处理输入码元并且提供对应于基站14的发射天线28数量的"n"个输出。 STC encoder logic 60 will process the input symbols and provides a corresponding number of transmit antennas of the base station 14 28 "n" outputs. 在上面关于图2被描述的控制系统20和/或基带处理器22将向控制STC编码提供一个映射控制信号。 Above with respect to FIG. 2 is depicted a control system 20 and / or baseband processor 22 will provide a mapping control STC encoding control signal. 此时,假定用于"n"个输出的码元表示将被发射的数据并且能够由移动终端16恢复。 In this case, assume that for "n" represents the output symbol and the data to be transmitted by the mobile terminal 16 can be restored.

[0052] 对于当前的例子,假定基站14具有两个天线28 (n = 2)并且STC编码器逻辑60 提供码元的两个输出流。 [0052] For the current example, assume the base station 14 has two antennas 28 (n = 2) and the STC encoder logic 60 provides two output streams of symbols. 因此,STC编码器逻辑60输出的每个码元流都被发送给对应IFFT 处理器62,其被单独地说明以便于理解。 Thus, each symbol stream the STC encoder logic 60 is sent to output a corresponding IFFT processor 62, which is illustrated separately to facilitate understanding. 本领域技术人员将认识到,一个或多个处理器可以被用来单独或结合此处所述的其它处理来提供这类数字信号处理。 Those skilled in the art will recognize that one or more processors may be used alone or to provide such digital signal processing in combination with other processing described herein. IFFT处理器62将优选地操作各个码元以提供傅里叶逆变换。 The IFFT processors 62 will preferably operate the respective symbols to provide an inverse Fourier transform. IFFT处理器62的输出提供时域中的码元。 Output of the IFFT processors 62 provides symbols in the time domain. 时域码元被分组成与前缀插入逻辑64的前缀相关联的帧。 Time domain symbols are grouped into frames with prefix insertion logic 64 associated with a prefix. 得到的每个信号经由对应的数字上变换(DUC)和数字-模拟(D/A)转换电路66在数字域中被上变换成中频并且被转换成一个模拟信号。 Each signal obtained by converting the corresponding digital (the DUC) and digital - analog (D / A) conversion circuit 66 is converted into an intermediate frequency in the digital domain and converted into an analog signal. 然后,得到的(模拟)信号在期望的RF频率上同时被调制,放大,并且经由射频电路68和天线28被发射。 Then, the resultant (analog) signals are simultaneously modulated at the desired RF frequency, amplified, and transmitted via the RF circuitry 68 and antenna 28. 特别地,预定移动终端16所知的导频信号在子载波当中被散布。 In particular, the mobile terminal 16 a predetermined known pilot signal is spread among the subcarriers. 将在下文中详细讨论的移动终端16将使用导频信号来进行信道估计。 The mobile terminal 16 discussed in detail below will use the pilot signals for channel estimation.

[0053] 现在,参考图5来说明由移动终端16发射的信号的接收。 [0053] now be described with reference to FIG. 5 receives signals transmitted by the mobile terminal 16. 只要被发射的信号到达移动终端16的每个天线40,各个信号就通过对应的射频电路70被解调并放大。 As long as the transmitted signal reaches the antenna 16 of each mobile terminal 40, via the respective corresponding signal to the RF circuit 70 is demodulated and amplified. 为了简洁并且清楚起见,只有两个接收路径中的一个被描述并详细地说明。 For brevity and clarity, only one of the two receive paths is described and explained in more detail. 模拟-数字(A/D)转换器和下变换电路72数字化并下变换该模拟信号以便数字处理。 Analog --72 digitized digital (A / D) converter and down-conversion circuit and converts the analog signals to the digital processing. 得到的数字化信号可以被自动增益控制电路(AGC) 74用来基于接收信号电平来控制射频电路70中的放大器增益。 The digitized signal can be obtained an automatic gain control circuit (AGC) 74 based on the received signal level is used to control the RF circuit 70 of the amplifier gain.

[0054] 开始,数字化信号被提供给同步逻辑15,其包括粗同步逻辑78,其缓冲几个0FDM码元并且计算两个连续的OFDM码元之间的自相关性。 [0054] starts, the digitized signal is provided to synchronization logic 15, autocorrelation between the two consecutive OFDM symbol includes coarse synchronization logic 78, which buffers several symbols and calculates 0FDM. 对应于相关性结果的最大值的最终时间指数确定一个细同步检索窗,其被细同步逻辑80用来基于报头来确定精确的帧开始位置。 Corresponding to the maximum value of the correlation result determines a final time index fine synchronization search window, which is used by fine synchronization logic 80 to determine a precise header based on the frame start position. 细同步逻辑80的输出易于帧定位逻辑84的帧获得。 Output of the fine synchronization logic 80 logical frame easy positioning frame 84 is obtained. 恰当的帧定位是重要的,以便随后的FFT处理提供了从时域向频域的准确转换。 Proper frame alignment is important so that subsequent FFT processing provides an accurate conversion from the time domain to the frequency domain. 细同步算法是基于报头携带的被接收导频信号和已知导频数据的局部拷贝之间的相关性。 The fine synchronization algorithm is based on the header is carried by a correlation between the received pilot pilot signal and the local copy of the known pilot data. 只要帧定位获得存在,OFDM码元的前缀就用前缀移除逻辑86来移除,并且得到的抽样被发送给频率偏移校正逻辑88,其补偿由发射机和接收机中的不匹配局部振荡器所引起的系统频率偏移。 As long as the presence of frame alignment is obtained, on the prefix of the OFDM symbol is removed with prefix removal logic 86 and resultant samples are sent to frequency offset correction logic 88, which compensates the local oscillation does not match the transmitter and receiver by is the system frequency offset caused. 优选地,同步逻辑76包括频率偏移和时钟估计逻辑82,其是基于报头来帮助估计对被发射信号的这类影响并且向校正逻辑88提供那些估计以便适当地处理OFDM码元。 Preferably, the synchronization logic 76 includes frequency offset and clock estimation logic 82, which is based on the headers to help estimate such effects on the transmitted signal and provide those estimations to the correction logic 88 to properly process OFDM symbols.

[0055] 此时,时域中的OFDM码元准备通过使用FFT处理逻辑90向频域转换。 [0055] At this time, OFDM symbol in the time domain are ready by using FFT processing logic 90 to frequency domain conversion. 结果是频域码元,其被发送给处理逻辑92。 The results are frequency domain symbols, which are sent to processing logic 92. 处理逻辑92用分散导频提取逻辑94来提取分散的导频信号,基于被提取的导频信号用信道估计逻辑96来确定信道估计,并且用信道重建逻辑98 为所有子载波提供信道响应。 The processing logic 92 pilot extraction logic 94 with scattered pilot extracted scattered pilot signal based on the extracted pilot signal using channel estimation logic 96 determines a channel estimate, and all sub-carriers provides channel responses using channel reconstruction logic 98 is. 为了为每个子载波确定一个信道响应,导频信号基本上是多个导频码元,它们用已知模式在时间和频率中分散在OFDM子载波各处的数据码元当中。 In order to determine a channel response for each subcarrier, the pilot signal is essentially multiple pilot symbols, they are dispersed throughout the data symbols among OFDM sub-carriers in a known pattern in both time and frequency. 图15说明了在OFDM环境中在给定的时间和频率图上的可用子载波当中的示例性的导频码元分散。 15 illustrates an exemplary guide on the available subcarriers in an OFDM environment at a given time and frequency plot symbols among the pilot dispersion. 继续图5,处理逻辑比较已接收的导频码元与某个时间在某个子载波中可预期的导频码元,以便为其中发射导频码元的子载波确定信道响应。 Continuing with Figure 5, the processing logic comparing the received pilot symbols to a time in a certain sub-carrier that can be expected pilot symbol, to transmit the pilot symbol subcarriers in which the channel response is determined. 结果被内插来为大多数(如果不是全部的话)剩余的没有提供导频码元的子载波估计信道响应。 The results are interpolated to for most (if not all) the remaining sub-carriers do not provide the estimated pilot symbol channel response. 实际和内插的信道响应被用来估计总的信道响应,其包括OFDM信道中的大多数(如果不是全部的话)子载波的信道响应。 The actual and interpolated channel responses are used to estimate the overall channel response, which includes most of the OFDM channel (if not all) sub-carriers in the channel.

[0056] 从每个接收路径的信道响应中导出的频域码元和信道重建信息被提供给STC解码器100,其提供两个接收路径上的STC解码来恢复被发射的码元。 [0056] derived from the channel responses for each receive path in the frequency-domain symbols and channel reconstruction information is provided to an STC decoder 100, which provides STC decoding on both received paths to recover the transmitted symbols. 信道重建信息把均等信息提供给STC解码器100,足以在处理各个频域码元的时候移除传输信道的影响。 The channel reconstruction information provides equalization information to the STC decoder 100 sufficient to remove the effects of the transmission channel when processing the respective frequency domain symbols.

[0057] 被恢复的码元用码元去交织器逻辑102按顺序被放回去,码元去交织器逻辑102 对应于发射机的码元交织器逻辑58。 [0057] The recovered symbols by the symbol deinterleaver logic 102 in order to be put back, the symbol deinterleaver 102 corresponds to a logic symbol interleaver logic 58 of the transmitter. 然后,去交织的码元被解调或者用去映射逻辑104被去映射成一个对应的比特流。 Then, the deinterleaved symbols are demodulated or de-mapping logic 104 to be mapped to a corresponding bitstream. 然后,比特用对应于发射机结构的比特交织器逻辑54的比特去交织器逻辑106被去交织。 Then, bit by bit corresponding to the bit interleaver logic 54 of the transmitter structure deinterleaver logic 106 is de-interleaved. 然后,去交织的比特被速率去匹配逻辑108处理并且被呈现给信道解码器逻辑110来恢复最初被扰码的数据和CRC校验和。 Then, the deinterleaved bits are rate de-matching logic 108 and presented to the processing channel decoder logic 110 to recover the initially scrambled data and the CRC checksum. 因此,CRC逻辑112移除CRC校验和,用传统方式来检查被扰码的数据,并且将其提供给去扰码逻辑114,以便用已知的基站去扰码代码来去扰码,从而恢复最初被发射的数据116。 Accordingly, CRC logic 112 is removed and the CRC checksum, in a conventional manner to check the data to be scrambled, and provides it to the de-scrambling logic 114 for de-scrambling code in the scrambling code known to the base station come, thereby recovering data originally transmitted 116.

[0058] 在恢复数据115的同时,CQI或在基站14至少足以创建CQI的信息被确定并且被发射到基站14。 [0058] While the recovery of data 115, CQI at the base station 14 or at least sufficient to create a CQI information is determined and transmitted to the base station 14. 如上所述,CQI可以是载波干扰比(CR)或者信道响应在OFDM频带中的不同子载波中变化程度的函数。 As described above, CQI may be a carrier level of interference in different sub-carriers in the OFDM frequency band vary as a function of the ratio (CR) or the channel response. 对于这个实施例,被用来发射信息的OFDM频带中的每个子载波的信道增益被相互比较,以便确定通路增益在OFDM频带中的变化程度。 For this embodiment, it is used to transmit the channel gain of each subcarrier in the OFDM frequency band information are compared with each other, in order to determine the degree of variation in the gain path in the OFDM frequency band. 尽管很多技术可以用来测量变化度,然而一个技术是计算在被用来发射数据的OFDM频带各处的每个子载波的信道增益的标准偏差。 Although many techniques can be used to measure the degree of change, however, a technique is the standard deviation calculated for each sub-carrier throughout the OFDM frequency band being used to transmit the data channel gain.

[0066] 通常,BS和移动终端之间的最佳下行链路(DL)操作利用来自移动终端的反馈,这通常为本领域技术人员所知并且因此在下文中被称为"移动用户站"(MSS)。 [0066] Generally, the best downlink (DL) between the BS and the mobile terminal by using the feedback from the mobile terminal, which is generally known to those skilled in the art and are therefore referred to as "mobile subscriber station" hereinafter ( MSS). 虽然用户站指示一个预订服务的装置,但是应当理解,本发明实施例可应用的更多普通无线终端可能不是任何服务的用户并且可能不一定是移动的。 While the user station a reservation instruction device and services, it should be understood that additional embodiments may be ordinary wireless terminal embodiment of the present invention may be applied not service any user and may not necessarily be mobile. 那些类型的反馈包括DL信道质量指示(CQI)反馈、DL MMO(多入多出)模式和置换选择、物理信道报告等等。 DL include those types of feedback channel quality indication (CQI) feedback, DL MMO (MIMO) mode and a permutation selected physical channel reports, etc. 此外,还存在与上行链路(UL)操作相关的其它反馈,比如MSS UL发射功率头空间。 In addition, there are other feedback related to an uplink (UL) operation, such as MSS UL transmit power head space.

[0067] 为了易于下行链路数据传输,诸如C/1测量(接收的信号功率除以噪声加上干扰功率)和MSS指示(比如MMO置换模式)之类的一些信息从MSS被传输到BS。 [0067] For ease of downlink data transmission, such as C / 1 measurement (the received signal power divided by the noise plus interference power) indication and the MSS (for example the replacement mode MMO) like some of the information is transmitted from the MSS to the BS. [0068] 在IEEE802.16e标准中,快速反馈信道被引入来实现这类UL传输。 [0068] In the IEEE802.16e standard, the fast feedback channel is introduced to implement such a UL transmission. 快速反馈信道使用专用CQI信道来发射除了CQI之外的有限数量的反馈信息。 Fast feedback channel using a dedicated CQI channel to transmit a limited amount of feedback information in addition to the CQI. 两种类型的快速反馈操作被建立,其中: Two types of fast feedback operation is established, in which:

[0069] I)单播快速反馈分配子报头被用来让MSS在一个临时分配的快速反馈信道上反馈四种类型信息中的一种;和 [0069] I) the unicast fast feedback allocation subheader is used to allow a fast feedback channel in an MSS temporarily assigned one of four types of feedback information; and

[0070] 2)广播信道分配信息元(IE)被用来用定期时机分配专用反馈信道以便让MSS能够向BS提供一个其MMO相关反馈的指示。 [0070] 2) a broadcast channel allocation information element (IE) is used to assign a dedicated feedback channel to allow the MSS with a regular timing to provide an indication of its MMO related feedback to the BS.

[0071] 两种上述的方法提供了准周期的时机以便让MSS能够提供其指示和反馈。 [0071] two of these methods provides a quasi-periodic so that the timing of their indication and the MSS to provide feedback. 与快速反馈操作有关的进一步说明在共同未决的美国专利申请号〈代理人案号71493-1329〉中被找到,其被指定给本申请的受让人并且在此通过参考被合并。 And instructions for fast feedback operations further in copending U.S. Patent Application No. <Attorney Docket No. 71493-1329> was found, which is assigned to the assignee of this application and is incorporated herein by reference.

[0072] 在某些情况中,如果MSS需要基于某些实时要求来告知其意图并且需要BS具有快速反应(例如,快速锚定BS切换、MMO模式切换、UL资源请求等等),则上述两个方法可能不是执行这项任务的有效方法,特别是如果MSS具有被分配用于定期报告的专用反馈信道并且来自MSS的指示不希望非常频繁地改变,因此周期被设置为一个长持续时间。 [0072] In some cases, if the MSS needs to be based on some real-time requirements and needs to inform the BS of its intended a rapid reaction (e.g., anchor BS fast switching, MMO mode switching, UL resource request, etc.), the above-described two a method may not perform this task effective way, especially if the MSS is allocated for periodic reports having a dedicated feedback channel and an instruction from the MSS undesired change very frequently, and therefore a long period is set to duration.

[0073] 在本发明的某些实施例中,假定每个MSS都具有一个专用的反馈信道。 [0073] In certain embodiments of the present invention, each MSS has assumed a dedicated feedback channel. 这类专用反馈信道的一个例子是信道质量指示信道(CQICH),其允许MSS向BS提供与BS和MSS之间的通信信道质量有关的反馈。 An example of such a dedicated feedback channel is a channel quality indicator channel (CQICH), which allow the MSS provides information about the quality of the communication channel between the BS and the MSS feedback to the BS. 例如,专用信道可以如共同未决的美国专利申请号〈代理人案号71493-1329〉中所述由CQICH分配信息元(CQICH Alloc IE)来分配,或者如下所述通过信道分配IE来分配。 For example, the channel may be dedicated as copending U.S. Patent Application No. <Attorney Docket No. 71493-1329> in the CQICH allocation information from the element (of Alloc IE CQICH) allocated, or a channel allocation IE to allocate by the following.

[0074] 在某些实施例中,由BS分配的专用反馈信道允许传输4比特的反馈信息。 [0074] In certain embodiments, the allocated feedback channel by the BS allows dedicated transmission of feedback information of 4 bits. 一个增强的专用反馈信道允许6比特的传输。 An enhanced dedicated feedback channel allows transmission of 6 bits. 一般地说,由反馈信道传输的比特数可以不同于特别地如上所述的4比特或6比特。 In general, the number of bits transmitted over the feedback channel may be different from 6-bit or 4-bit specifically described above. 然而,比特数优选地小于10比特。 However, preferably the number of bits less than 10 bits.

[0075] 实现反馈的第一实施例现在将关于图7被描述。 [0075] The first embodiment implements feedback will now be described with respect to FIG. 在所描述的特殊实施例中,在600,MSS向BS发送周期的C/Ι报告。 In a particular embodiment of the described embodiment, in 600, MSS C / Ι report to the BS transmitting period. 定期报告在该专用信道上被发送。 Periodic report is transmitted in the dedicated channel. 在一个随后的时间点,如在610所指出,通过在专用反馈信道上向BS发射一个预保留的反馈有效载荷代码(例如1111),MSS自发地向BS指出其发送反馈信息的意图。 In a later point in time, as indicated at 610, by transmitting the feedback payload codes (e.g., 1111) a pre-reserved dedicated feedback channel to the BS, the MSS to the BS noted spontaneously transmits feedback information is intended.

[0076] 响应于这个预保留的反馈有效载荷代码,如在620所指出的,BS向MSS发送一个信息元(IE),其分配用于MSS的上行链路资源以便发送包括该反馈信息的MSS反馈。 [0076] In response to this feedback payload code is pre-reserved, as indicated at 620, the BS transmits a message to the MSS element (IEs), which allocate uplink resources for the MSS to transmit the feedback information including MSS feedback. 在某些实施例中,如在美国专利申请〈代理人案号71493-1329〉中所述,IE可以是一个"MMOUL基础"IE,其被用于分配UL传输资源。 In certain embodiments, as described in <Attorney Docket No. 71493-1329> U.S. Patent Application, IE may be a "MMOUL base" IE, which is used for UL transmission resources allocated. BS在数据帧的普通上行链路资源分配映射分量部分内发送上行链路资源分配IE,比如图6中的映射分量214。 BS uplink data frame in a normal link resource allocation map component portion transmitted uplink resource allocation IE, such as mapping component 6214 in FIG. 在某些情况下,MSS反馈包括诸如基本连接标识(CID)、反馈类型和反馈内容之类的信息。 In some cases, MSS such as a basic connection identification comprises a feedback (CID), the type of feedback information and the feedback content or the like. 然后在630,MSS通过已分配的上行链路资源在MAC PDU中向BS发送MSS反馈信息。 Then at 630, MSS feedback information through the uplink resource allocated to the MSS transmits BS in the MAC PDU. 被分配为上行链路资源的MACPDU在如上所述的图6的数据帧205中的UL子帧219的区域224被发现。 Allocated uplink resource MACPDU data frames as described above in FIG. 6 205 219 UL subframe region 224 is found. MSS发送MSS反馈信息630可以发生在与上行链路资源分配IE被发送620相同的数据帧中,或者它可以在一个后续数据帧中发送该MSS反馈信息。 MSS MSS transmits feedback information 630 may be transmitted occur in the same data frame 620 and uplink resource allocation IE, or it may send feedback information to the MSS a subsequent data frame.

[0077] 如在下文中将更详细地描述的,上述信令示例中的MSS反馈信息以下列任意一种形式被发送:1)反馈报头,2)反馈微型报头,或3)MAC PDU中的子报头。 [0077] As described in greater detail below, the above signaling examples MSS feedback information is transmitted in any of the following forms: 1) the feedback header, 2) feedback mini-header, or 3) MAC PDU in the sub header. 反馈报头和反馈微型报头是一个更普通的MAC PDU报头的特例。 Feedback Feedback header and a mini-header is a special case of the more general MAC PDU header. 反馈报头和反馈微型报头是一般放在MAC有效载荷之前的MACPDU的一部分。 Feedback header and feedback mini header part is generally placed before the MACPDU MAC payload. 在某些实施例中,它们包括为与MAC PDU内容相关的I3DU所特有的信息,例如用于BS和特殊MSS之间的通信链路的连接标识符(CID)。 In certain embodiments, they are associated with the MAC PDU including I3DU specific content information, for example, connection identifiers for a communication link between the BS and the particular MSS (CID). 反馈子报头是更普通的MAC PDU子报头的一个特例。 Feedback subheader is a special case of the more general MAC PDU sub-header. 反馈子报头是可以被包括在MAC PDU中的另一个分量。 Feedback subheader other component can be included in the MAC PDU. 在典型情况下,子报头位于MAC PDU报头和MAC PDU有效载荷之间并且可以被用于BS和MSS之间的信息传输。 In a typical case, the sub-header is located between the MAC PDU and the MAC PDU header and payload may be used for transmission of information between the BS and the MSS.

[0078] 上述实施例还可以被用作MSS用于请求额外上行链路资源的预备步骤。 [0078] The above embodiments also be used as a preliminary step for the MSS to request additional uplink resources. 响应于接收到预保留的反馈有效载荷代码,BS分配一个特殊大小的上行链路资源,例如6个字节。 In response to receiving the feedback payload pre-reserved codes, the BS allocates an uplink resource of a particular size, for example 6 bytes. 替代于使用该6个字节来发射反馈信息,MSS可以使用该6个字节分配来发射对更合适大小的UL发射资源的请求。 Instead of using the 6 bytes to transmit feedback information, MSS can use the six bytes allocated transmission resources to transmit the request for a more suitable size UL. 这类请求的一个例子是带宽请求报头。 An example of such a request is a bandwidth request header.

[0079] 在某些实施例中,每当MSS具有要发送给BS的反馈信息,它就发送一个预保留的有效载荷代码。 [0079] In certain embodiments the code payload embodiments, whenever the MSS has to send feedback information to the BS, it sends a pre-reserved.

[0080] 预保留有效载荷代码是任何特殊的N比特的有效载荷值,其被建立成被认为是MSS希望发送反馈信息的指示,其中,"N"是用于在反馈信道上传输的比特数。 [0080] The pre-reserved special code is any payload payload value of N bits, which are considered to be established as desired MSS transmits feedback indication information, wherein, "N" is the number of bits for feedback transmission channel .

[0081] 当所使用的反馈信道被实现用于4比特时,预保留的有效载荷比特被设置并且在上行链路信道描述(U⑶)中被保存为一个特殊的信道编码值。 [0081] When a feedback channel is used to implement 4-bit, payload bits are pre-reserved and are stored as a set of special value in channel encoded uplink channel description (U⑶) in. 优选地,N比特有效载荷值不全是零。 Preferably, N-bit payload is not all zero value. 优选地,当反馈信道是被实现用于6比特的增强式快速反馈信道时,预保留代码是ObllllO。 Preferably, when the feedback channel is 6 bits be implemented for the fast feedback channel enhancement type, the pre-reservation code ObllllO.

[0082] 如果MSS通过使用预保留的N比特有效载荷代码和反馈报头而支持反馈方法,则一个值"M"被定义为UCD中的预保留的N比特有效载荷代码。 [0082] If the MSS by using the pre-reserved codes N-bit payload header is feedback and feedback support method, a value of "M" is defined as the pre-UCD remaining N-bit payload code. 为了避免预保留有效载荷代码与在与该预保留有效载荷代码相同的信道上传输的被计算CQI发生冲突的情况,如果一个计算的CQI有效载荷值被发现等于值"M",则MSS把CQI有效载荷比特设置成一个等于"M-1"而不是"M"的值。 In order to avoid pre-reserved reserved payload code conflict condition is calculated CQI payload same transmission channel in the pre-code, a CQI payload if the calculated value is found equal to the value "M", the MSS the CQI payload bits set to a value "M-1" instead of "M" is equal.

[0083] 在也具有一个专用反馈信道的另一个实施例中,其以举例的方式在图8中被说明,BS使用一个未经请求的轮询方法来指出其对反馈信息的请求。 [0083] In another have a dedicated feedback channel embodiment, which is illustrated by way of example in FIG. 8, BS using an unsolicited polling method to indicate its request for feedback information. 该轮询方法涉及使用诸如图6中的ULIE215之类的IE,其由BS发送来调度由MSS执行的MSS反馈信息传输。 The method involves the use of polling IE ULIE215 such as in FIG. 6, which is transmitted by the BS to the MSS performs the scheduling of the feedback information transmitted by the MSS. 特殊IE的一个例子是在下面将被更详细地描述的"反馈轮询"IE。 IE is a specific example of "Feedback Polling" IE will be described in more detail below. BS在700发送轮询IE,其指出在数据帧的更普通上行链路资源分配映射分量(比如图6中的映射分量214)部分内由BS到MSS所希望的反馈类型。 IE BS transmits poll 700, indicated in its more general mapping of uplink resource allocation component data frames (such as in FIG mapping component 6214) by the BS to the MSS inner portion desired feedback type. 在710指出,MSS使用专用反馈信道在下一帧中报告所期望的反馈信息。 Indicated at 710, MSS using a dedicated feedback channel in the next frame the desired report feedback information. 在某些实施例中,轮询和报告的处理如BS所期望的那样经常发生。 In certain embodiments, the polling process and BS reports as often as desired.

[0084] 在某些实施例中,MSS不具有被分配用于向BS的反馈传输的专用反馈信道。 [0084] In certain embodiments, MSS does not have to be allocated for feedback transmission to the BS a dedicated feedback channel. 因此,BS分配将被MSS用于发射反馈信息的临时反馈信道。 Thus, BS MSS is allocated a temporary feedback channel for transmitting feedback information.

[0085] 参考图9,在不具有专用反馈信道的第一个这样的实施例中,BS通过使用由BS发送的IE来使用一个未经请求的轮询方法以调度由MSS执行的MSS反馈传输。 [0085] Referring to FIG 9, in a first embodiment does not have such a dedicated feedback channel of, by using a BS IE transmitted by the BS using a polling method to schedule MSS unsolicited feedback transmission performed by the MSS . 类似于用于存在专用信道的情况的上述轮询IE,这个实施例中的轮询IE包括MSS用于报告的所期望的反馈类型。 Similar to the above-described polling IE for the presence of a dedicated channel, this embodiment includes a feedback type polling IE for reporting the MSS desired embodiment. 另外,BS在将被用于MSS反馈传输的数据帧中也分配一个临时反馈信道。 Further, BS data frame to be used for feedback transmission in the MSS is also assigned a temporary channel feedback. 如800所示,BS发射轮询IE,其指出BS期望的反馈类型以及临时分配的反馈信道的标识。 As shown in 800, BS transmits a polling IE, which indicates the BS identifies the desired type of feedback and the feedback channel temporarily allocated. 如在810指出,MSS使用临时分配的反馈信道在下一帧中报告BS请求的期望反馈信息。 As indicated at 810, MSS using feedback channel temporarily allocated BS requests a desired report feedback information in the next frame. 这个例子中使用的轮询IE是"反馈轮询"IE,其将在下面被更详细地描述。 Polling IE used in this example is "Feedback Polling" IE, which will be described below in more detail.

[0086] 在图8和9中,MSS在专用或临时分配信道上发送MSS反馈信息可以在与轮询IE被发送相同的数据帧中发生,或者它可以在一个后续数据帧中发送MSS反馈信息。 [0086] In Figures 8 9, MSS transmits a dedicated channel or a temporary allocation of MSS feedback information may occur in a data frame is transmitted in the same polling IE, or it may send feedback information MSS a subsequent data frame .

[0087] 在图8和9的例子中,替代于用轮询IE向MSS发射一个轮询指示,BS可以如美国专利申请号〈代理人案号71493-1329〉中所述的用快速反馈子报头来指出BS请求的反馈类型和MSS用于发射BS所请求的反馈的上行链路资源(专用信道或临时分配信道)的位置。 [0087] In the example of FIGS. 8 and 9, instead of indicating the MSS transmits a polling polling IE, BS may be as described in US Patent Application No. <Attorney Docket No. 71493-1329> in the flash feedback sub feedback header type noted BS and the MSS request uplink resources for transmitting the location of the requested feedback BS (or a temporary dedicated channel allocation channel).

[0088] 参考图10,其中不存在专用反馈信道的另一个实施例现在将被描述。 [0088] Referring to FIG 10, where another dedicated feedback channel is not present embodiment will now be described. BS用另一形式的未经请求的轮询方法让MSS能够发送MSS反馈信息。 BS polling method using another form of unsolicited allow MSS MSS can transmit the feedback information. 如在900指出的,BS使用上行链路资源分配IE (例如,上述的"MMOUL基本"IE)来分配MSS用于发射反馈信息的UL传输资源,而不是如在之前所述的实施例中发送轮询IE。 As indicated in 900, the BS using the uplink resource allocation IE (e.g., the above-described "MMOUL substantially" IE) used for transmitting the feedback MSS allocated UL transmission resource information, rather than transmission as described in the prior embodiment polling IE. BS在数据帧的一个更普通的上行链路资源分配映射分量部分内发送上行链路资源分配IE。 BS in a data frame transmitted uplink resource allocation IE within the more general mapping of uplink resource allocation component portion. 分配UL传输资源包括在数据帧中IE发射UL传输资源位置。 UL allocation of transmission resources includes transmitting the data frames IE UL transmission resource location. 如在910指出的,MSS用上行链路资源分配IE所分配的UL资源向BS发射包括MSS反馈信息的MACPDU。 As indicated at 910, the UL resources MSS uplink resource allocation IE allocated transmit feedback information MACPDU comprises MSS to the BS. MSS发送MSS反馈信息910可以发生在与上行链路资源分配IE被发送900相同的数据帧中,或者它可以在一个后续数据帧中发送该MSS反馈信息。 MSS MSS transmits feedback information 910 may be transmitted occur in the 900 same uplink resource allocation IE data frame, or it may send feedback information to the MSS a subsequent data frame.

[0089] 如在下文中将被更详细地描述的,上述信令例子中的MSS反馈信息以下列任意一种形式被发送:反馈报头;反馈微型报头;*MAC PDU中的子报头。 [0089] As is described in more detail hereinafter, examples of the above-described signaling MSS feedback information is transmitted in the form of any of the following: the feedback header; micro feedback header; * sub-header in the MAC PDU.

[0090] 上述实施例的一个优点是基于实时要求实现了快速反应,比如快速锚定BS切换、快速MMO模式切换或用于UL业务的及时UL资源分配。 One advantage of the [0090] above-described embodiment is based on the real-time requirements to achieve a rapid reaction, such as anchor BS fast switching, mode switching or MMO fast UL resource allocation in time for UL traffic.

[0091]"反馈轮询"IE [0091] "Feedback Polling" IE

[0092] 来自BS的定期轮询以IE的形式向MSS发射用于一帧的大量分配。 [0092] The periodic polling IE from the BS in the form of transmitting to the MSS for the mass distribution a. 对于每个分配,BS指出一个专用信道是否先前被分配或者一个反馈信道是否需要被临时分配。 For each allocation, BS indicates whether a previously allocated dedicated channel or whether a feedback channel is required to be temporarily assigned. 如果专用信道先前被分配,则BS发射一个专用信道的标识,反馈将在该专用信道上被传输。 If the previously allocated dedicated channel, the BS transmits a dedicated channel is identified, the feedback to be transmitted in a dedicated channel. 如果反馈信道需要被临时分配,则BS在该帧的上行链路部分中标识将用于发射反馈类型和反馈内容的反馈信道的位置。 If the feedback channel needs to be temporarily assigned, the BS in the uplink portion of the frame identified in the feedback channel for transmitting the position feedback type and feedback content. 然后,BS在被分配的反馈信道上指出反馈类型。 Then, BS indicated in the feedback type feedback channel allocated.

[0093] 用于调度IE的语法示例在被标识为"反馈轮询"IE的表I中被示出,该IE用于上面关于图8和9所描述的MSS的未经请求轮询。 Syntax example of scheduling of IE [0093] intended to be identified as shown in the "Feedback Polling" IE in Table I, above the unsolicited polling IE for about MSS depicted in FIG. 8 and 9 in. 在某些实施例中,"反馈轮询"IE被设计成无论是否存在专用信道都可以被使用。 In certain embodiments, "Feedback Polling" IE is designed as a dedicated channel regardless of whether there may be used. 表I的"反馈轮询"IE用一个"反馈信道分配指示符"字段来指出反馈信道是否已经被专用或者反馈信道是否需要临时被分配。 Table I "Feedback Polling" IE "feedback channel allocation indicator" field is used to indicate whether a feedback channel has been whether or dedicated feedback channel needs to be temporarily assigned. "反馈信道分配指示符"字段怎样被设置确定了BS是否需要分配临时反馈信道。 "Feedback channel allocation indicator 'field is set how the BS determines whether a feedback channel needs to be allocated a temporary. 如果反馈信道需要被临时分配,则"反馈信道分配指示符"字段比特被设置等于"O",因此对于这个举动将做出规定。 If the feedback channel needs to be temporarily assigned, the "feedback channel allocation indicator" field bits is set equal to "O", and therefore make provisions for this will move. 如果反馈信道不需要被临时分配,则"反馈信道分配指示符"字段比特被设置等于"I",并且专用反馈信道用"信道质量指示符ID(CQICH ID)"字段被适当地标识。 If the feedback channel need not be temporarily assigned, the "feedback channel allocation indicator" field bits is set equal to "I", and the dedicated feedback channel with a "channel quality indicator ID (CQICH ID)" field is appropriately identified. 只要反馈信道的条件被建立,BS期望的反馈类型就用"反馈类型"字段被设置。 As long as the channel feedback condition is established, BS desired type of feedback to use "feedback type" field is set.

[0111] 当前在无线OFDM MMO系统中已知的快速反馈的一个例子是BS用来轮询MSS以便在快速反馈信道上提供高达四种类型反馈的DLFAST_FEEDBACK子报头(在美国专利申请〈代理人案号71493-1329〉中被更详细地描述)。 [0111] The currently known systems in a wireless OFDM MMO example of a fast feedback is used to poll the MSS BS in order to provide up to four types of DLFAST_FEEDBACK feedback subheader (in U.S. Patent Application <Attorney Docket fast feedback channel No. 71493-1329 described> in more detail below). 然而,为了支持与MMO信道相关的反馈和支持UL操作其它方面的反馈,更多数量的反馈类型希望,以及用于为这些额外的反馈类型发射反馈内容的关联的附加容量被定义。 However, to support MMO channel related feedback and support other aspects of the UL feedback operations, a greater number of types of feedback desired, as well as additional capacity for transmitting feedback associated with the content for these additional feedback type is defined. 一个新的轮询信令格式被希望定义来容纳多于现有的四种反馈类型。 Polling a new signaling format defined is desired to accommodate more than four conventional feedback type. 在特别包括反馈报头的本发明某些实施例中,比如通过使用DL FAST_FEEDBACK子报头,MSS能够比执行反馈的先前标识方法一次反馈更大容量的信息。 In particular, certain embodiments include a feedback header of the present invention, such as by using DL FAST_FEEDBACK subheader, the MSS can be performed than previously identified feedback information feedback method for a larger capacity.

[0112] 响应于来自BS的未经请求的轮询IE通过MSS发送的本发明的反馈报头具有将其标识为反馈报头,标识反馈类型并且包括反馈内容的字段。 [0112] IE in response to the polling request from the BS without having to identify it as the feedback header, and identifies the type of feedback includes a feedback field with the contents of the feedback header sent by an MSS according to the present invention. 反馈类型和反馈内容的一些例子在表2和4中被找到。 Some examples of the feedback type and feedback content is found in Table 2 and 4.

[0115] 表4的值"值"列中的二进制值与那些字段相关的特殊可选择选项相关联。 [0115] Table 4 is the value of the "Value" column in the binary value associated with the particular selectable option that is associated fields. 应当理解,每个特殊的二进制值仅仅是每个特殊选项的一个例子并且一个特殊的选项可以由具有任何合理比特数的任何适当二进制值来表示。 It should be understood that each specific binary value is merely an example of each particular option and a special options may be represented by any suitable binary value having any reasonable number of bits. 另外,其它类型反馈的编码(在此没有被特别地描述)可以被分配给预留的比特值。 Further, other types of feedback coding (here is not particularly described) may be assigned to a reserved bit values.

[0116] 反馈报头的一个实施例现在将关于图12被描述。 [0116] Feedback header according to one embodiment will be now described with respect to FIG. 12. 图12示出了反馈rou(协议数据单元)的一部分,该部分是反馈报头300。 FIG. 12 shows a part of a feedback ROU (protocol data unit), which is part of the feedback header 300. 反馈PDU位于图6的数据帧205中的UL子帧219的区域224。 FIG 6 is located in the feedback PDU data frame 205 in region 219 of the UL subframe 224. 反馈报头300包括"报头类型(HT)"字段310、"加密控制(EC)"字段320、"标准反馈报头/微型反馈报头指示(N/M)"字段330和"CID包含指示(CU)"字段350。 The feedback header 300 includes a "header type (the HT)" field 310, "Encryption Control (EC) 'field 320, the" standard Feedback header / micro feedback header indicates (N / M) "field 330 and" the CID comprises an indication (the CU) " field 350. 反馈报头300的剩余部分包括"反馈内容"字段360,"基本连接标识(CID)"字段370和"报头检查序列(HCS)"字段380。 The remaining portion of the feedback header 300 includes 'Content Feedback "field 360," the basic connection identification (the CID) "field 370 and the" header check sequence (the HCS)' field 380.

[0117] 反馈报头300的例子包括下列特性: Examples [0117] The feedback header 300 includes the following features:

[0118] a)反馈报头的长度是6字节(48比特); [0118] a) the feedback header length is 6 bytes (48 bits);

[0119] b) " HT"字段310被设置等于"I"并且"EC"字段320被设置等于"I"。 [0119] b) "HT" field 310 is set equal to "I" and "EC" field 320 is set equal to "I". 比特的这个结合被用来指出报头300是一个反馈报头; The combined bits is used to indicate a feedback header 300 is a header;

[0120] c)如下所述的"N/M"字段330被设置等于"O"来指出这是标准大小的反馈报头300 ; [0120] c) below according to "N / M" field 330 is set equal to "O" to indicate that this is a standard size of the feedback header 300;

[0121] d)"反馈类型"字段340根据所期望的反馈类型来设置,例如上表2中的项; [0121] d) "feedback type" field 340 depending on the desired type of feedback is provided, for example, a table entry 2;

[0122] e)对于具有CID字段的报头,"CII"字段350被设置等于"O",并且对于没有CID字段的报头被设置成I ;和 [0122] e) with respect to the CID field of the header, "CII" field 350 is set equal to "O", and not to the CID field of the header is set to I; and

[0123] f)"反馈内容"字段360用被提供给BS的反馈信息填满。 [0123] f) "Feedback Content" field 360 is provided with feedback information to the BS filled. 例如,反馈信息可以是基于表2中与特殊的"反馈类型"相关联的"反馈内容"项目。 For example, the feedback information may be based on Table 2 and special "feedback type" "Feedback Content" associated with the item.

[0124] 在图12中,每个字段括弧中的数字是被分配给那个字段的比特数。 [0124] In FIG. 12, each field figures in brackets are the number of bits are allocated to that field. 例如,"HT"字段中的比特数是"I","反馈类型"字段中的比特数是"4"而"反馈内容"字段中的比特数是"8"。 For example, "HT" is the number of bits in the field "I", the number of bits "feedback type" field is "4" and "Feedback Content" field is the number of bits "8." 在本发明的一个优选实施例中,反馈报头具有如图所示的48个比特。 In a preferred embodiment of the present invention, the feedback header with 48 bits as shown in FIG. 然而,一般地说,比特数取决于期望的反馈报头的大小是可变的。 Generally, however, the number of bits depending on the desired size of the feedback header is variable. 在某些实施例中,比特数可以仍然等于48,不过比特分配可以与图中所示不同地进行分配。 In certain embodiments, the number of bits equal to 48 can still, however, the bit allocation can be allocated differently than shown in FIG. 而且,在某些实施例中,不是图12中说明的所有字段都被包括在反馈报头中,并且得到的报头仍然将在本发明的范畴内被考虑,例如其中可以没有"基本CID"字段370。 Further, in some embodiments, all the fields are not FIG. 12 described are included in a feedback header, and the resulting header will still be considered within the scope of the invention, for example where there may be no "substantially the CID" field 370 .

[0125] 在某些情况中,因为反馈报头用BS分配的单播UL资源来发送,由于单播UL资源唯一地标识MSS,所以反馈报头300中的"基本CID"字段370是多余的并且将在专用信道上由MSS发送。 [0125] In some cases, because the unicast UL resource feedback header with a BS allocates to transmit, since the unicast UL resource uniquely identifies the MSS, so the feedback header 300 is "substantially the CID" field 370 is redundant and dedicated channel transmitted by the MSS. 从而,反馈报头300中的16比特的"基本CID"字段370可以被移除并且比特空间被用于发送更多的反馈信息。 Thus, the feedback header 300 in "the CID base" field is 16 bits and 370 bits can be removed more space is used to transmit feedback information.

[0126] 根据本发明的一个实施例,图13示出了没有"基本CID"字段370的反馈报头301。 [0126] According to one embodiment of the present invention, FIG. 13 shows not "substantially the CID" field in the feedback header 301 370. 这为将被发射的反馈内容360提供了更多空间。 This feedback provides more space for content to be transmitted 360. 反馈报头的其它字段与反馈roU300相同。 Feedback header fields and other feedback roU300 same. 类似于图12,每个字段的括弧中的数字表示被分配给该字段的比特数。 Similar to Figure 12 The numbers in parentheses in each field the number of bits assigned to the field.

[0127] 除了响应于反馈轮询IE或UL资源分配映射IE来使用反馈报头之外,反馈报头可以在反馈信息需要由MSS发送的时候在其它方案中被使用。 [0127] In addition to using the feedback header in response to a feedback resource allocation polling IE or UL map IE addition, the feedback header may be used in another embodiment when the feedback information to be transmitted by the MSS. 例如,MSS通过发送一个带宽请求范围代码向BS自发地发送反馈报头,并且然后在接收到一个CDMA分配IE之后发送该报头。 For example, the MSS sent by transmitting a bandwidth request code to the BS range spontaneously feedback header and then transmit a header is received after the CDMA allocation IE. 在另一个例子中,MSS可以通过与UL业务一起发送报头向BS发送反馈报头。 In another example, MSS may be transmitted to the BS through the feedback header transmission header with UL traffic.

[0128] 反馈微型报头 [0128] Feedback header miniature

[0129] 根据本发明的另一个实施例提供了一个大小减小的反馈报头。 [0129] Providing a reduced size of the feedback header according to another embodiment of the present invention. 根据本发明的一个实施例,这个大小减小的反馈PDU包括反馈微型报头并且不包括有效载荷。 According to one embodiment of the present invention, the reduced size micro feedback includes a feedback PDU does not include a header and a payload. 根据本发明实施例的大小减小的反馈报头在图14中被示出,通常在500被指出。 According to an embodiment of the present invention, the size of a reduced feedback header is shown in FIG. 14, is generally indicated at 500. 大小减小的反馈报头500包括"HT"字段510、" EC"字段520、" N/M类型"字段530。 Reducing the size of the header 500 comprises a feedback "the HT" field 510, "EC" field 520, "N / M Type" field 530. 大小减小的报头500的剩余部分包括"反馈内容"字段550和"HCS"字段560。 Reducing the size of the remaining portion of the header 500 includes' Content Feedback "field 550 and" the HCS "field 560.

[0130] 大小减小的反馈报头500的一个例子具有下列特性: [0130] feedback message of reduced size example of a head 500 has the following characteristics:

[0131] a)报头500的长度是3字节(24比特); Length [0131] a) header 500 is 3 bytes (24 bits);

[0132] b) " HT"字段510被设置为I并且"EC"字段520被设置为1,其结合指出报头是一个反馈报头; [0132] b) "HT" field 510 is set to I and "EC" field 520 is set to 1, noted that binds a feedback header is a header;

[0133] c) " N/M"字段540被设置为I来指出这是一半大小的反馈报头; [0133] c) "N / M" field 540 is set to I to indicate this is half the size of the feedback header;

[0134] d)"反馈类型"字段540根据所期望的反馈类型来设置,例如上表2中的项目;和 [0134] d) "feedback type" field 540 depending on the desired type of feedback is provided, for example, a list of items 2; and

[0135] e)因此,根据"反馈类型"字段的选择值,"反馈内容"550字段例如基于表2中的项目来设置。 [0135] e) Thus, according to the selection value "feedback type" field, a "Feedback Content" field 550, for example, in Table 2 based on the item set.

[0136] 当MSS在单播UL资源上发送反馈报头时,MSS可以基于反馈类型和反馈信息量来决定反馈报头的大小(即,标准反馈报头或大小减小的反馈微型报头)。 [0136] When the MSS transmits the feedback header in the unicast UL resources, MSS may be based on the type and amount of feedback information feedback to determine the size of the head (i.e., standard feedback header or reduced size micro feedback header) feedback message.

[0137] 对于反馈报头,MSS报告IE和反馈微型报头、符合此处所述的本发明意图的其它反馈类型和反馈内容(但是没有被特别地包括在表2和4中)将在本发明的范畴内被考虑。 [0137] For the feedback header, the MSS report IE and the feedback mini-header, in line with the other feedback type described herein are intended in the present invention and a feedback content (but are not specifically included in Table 2 and 4) in the present invention. to be considered within the scope. 而且,虽然"反馈类型"和"反馈内容"字段的比特大小分别被描述为4比特和8比特,但是这些字段中的比特数可以大于或小于这些数。 Further, although the bit size of the "feedback type" and "Feedback Content 'field are described as 4-bit and 8-bit, but the number of bits of these fields may be greater or less than these numbers. [0138] 在本发明的一个优选实施例中,反馈报头具有如图所示的24比特。 [0138] In a preferred embodiment of the present invention, the feedback header has 24 bits as shown in FIG. 然而一般来说,比特数取决于所期望的反馈报头的大小是可变的。 In general, however, the number of bits depending on the desired size of the feedback header is variable. 在某些实施例中,比特数可以仍然等于24,不过比特分配可以与图中所示不同地分配。 In certain embodiments, the number of bits can still equal to 24, but allocated bit allocation may be different from that shown in FIG.

[0139] 微型反馈子报头 [0139] Micro Feedback subheader

[0140] 根据本发明的另一个实施例,MSS可以在一个微型反馈子报头中向BS发送反馈信息。 [0140] According to another embodiment of the present invention, MSS may send feedback information to the BS in a miniature feedback subheader. 子报头是MSS向BS发送的MAC PDU的一部分,其一般在MAC反馈PDU中位于报头之后。 Subheader part of the MAC PDU is transmitted to the MSS BS, which is typically after the MAC header is located in the feedback PDU. 子报头大多数经常存在于报头和H)U的内容或有效载荷之间,但是它可以位于PDU中的其它地方。 Most often subheader is present between the header and H) U content or payload, but it may be located elsewhere in the PDU. 这类微型反馈子报头的格式的示例在表5中被示出。 Examples of such micro-format feedback subheader is shown in Table 5.

[0143]"反馈类型"和"反馈内容"字段的例子在表2和表4中被找到。 [0143] Examples of the "feedback type" and "Feedback Content 'field is found in Table 2 and Table 4. 一般地说,符合此处所述的本发明意图的其它类型的反馈类型和反馈内容(不是被特别包括)将在本发明的范畴内被考虑。 In general, the present invention is intended to meet the herein other types of feedback type and feedback content (not specifically included) will be considered within the scope of the invention.

[0144] MIMO传输格式和信令设备被概括来提供一个多样性MMO方案,以便通过使用相同的空中接口设计来操作。 [0144] MIMO transmission format and signaling devices are summarized to provide a diversity MMO scheme, so as to operate by using the same air interface design. 在一些通信会话中,基本传输格式包括:(I)空间多路复用(SM)和(2)时空发射分集(STTD),例如具有基于2、3和4发射天线配置的矢量或矩阵加权的全MIMO或子MMO传输。 In some communication session, the basic transmission format comprises: (I) spatial multiplexing (SM) and (2) space-time transmit diversity (the STTD), for example, a vector or matrix based on the 2, 3 and 4 transmit antennas arranged weighted full MIMO transmission or sub-MMO.

[0145] 下列方案也被推广到多个基站传输。 [0145] The following scheme is also extended to a plurality of base station transmissions.

[0146] 为了利用反馈信道,该反馈信道必须首先被分配。 [0146] In order to use a feedback channel, the feedback channel must first be allocated. 本发明的实施例现在将关于图16来描述,图16说明了在MM00FDM系统中动态地向无线终端分配至少一个反馈信道的方法流程图。 Embodiments of the present invention will now be described with respect to FIG. 16, FIG. 16 illustrates a method of dynamically assigned to the radio terminal MM00FDM system in at least one feedback channel.

[0156] 如上所述的,在基站和无线终端或MSS之间的OFDM闭环(CL)MMO通信的某些情况中,终端向基站反馈信息,其允许基站提供将被终端接收的最佳信号。 [0156] As described above, certain conditions between the base station and the wireless terminal or the MSS OFDM closed loop (CL) MMO communication, the terminal feedback information to the base station, which allows the base station providing the best signal to be received by the terminal. 在OFDM CL MIMO通信的某些方面中,通常被称为奇异值分解(SVD)的数学处理方法被MSS用来确定BS到MSS传输的最佳条件,并且把这些信息反馈给BS以便在编码由BS传输的信息中被适当地使用。 In some aspects of the OFDM CL MIMO communication, often referred to mathematical treatment singular value decomposition (SVD) is used to determine the BS to the MSS MSS optimal transmission conditions, and the feedback information to the BS so that encoded by It is suitably used in the transmission of BS information. 在OFDM MMO通信的某些方面中,终端可以基于终端可测量的基本标准(例如,BS和MSS之间的信道功率强度)从用于向MSS传输下行链路信息的整个BS天线群中选择一个BS天线的子集。 In certain aspects OFDM MMO communication, the terminal may select the entire downlink transmission to the MSS BS antenna from a group of information based on the basic criteria (e.g., strength of the channel power between the BS and the MSS) terminal measurable BS antenna subset. 这些方面在美国专利号〈代理人案号71493-1334〉中被更充分地描述,该专利申请被分配给本申请的受让人并且在此通过参考被合并。 These aspects are more fully described in <Attorney Docket No. 71493-1334> U.S. Patent No., which patent application is assigned to the assignee of the present application and is incorporated by reference herein. 在前述的这两个方面中,至少一个反馈信道被用来让MSS向BS传递期望的信息。 In the foregoing two aspects, the at least one information channel is used to allow a desired MSS to a BS transmitting feedback.

[0160] 当使用SVD模式处理时,存在至少五种模式,对于这些模式使用某种形式的反馈。 [0160] When processing using the SVD mode, there are at least five modes, using some form of feedback for these modes. 第一模式涉及闭环和AMC频带置换。 The first relates to closed-loop mode and a band AMC permutation. 第二模式涉及包括差分编码的H矩阵。 The second mode involves matrix H includes differential encoding. 第三模式涉及包括差分编码的w矢量。 The third mode relates to a vector comprising a differential encoding w. 第四模式涉及包括差分编码的顶部X层的V和CQI。 The fourth mode is directed to a top of the V and X layer CQI differential encoding. 第五模式涉及包括差分编码的V和顶部X层的码本指数。 It relates to a fifth mode comprising codebook index differential encoding V X and the top layer. 其它模式在美国专利号〈代理人案号71493-1334〉中被描述。 Other modes are described in U.S. Patent No. <Attorney Docket No. 71493-1334> in.

[0161] 存在用于从MSS向BS提供反馈以用于SVD模式的多个实施例。 [0161] exist for providing feedback from the MSS to the BS in a plurality of modes for SVD embodiment. 在一个这样的实施例中,一个或多个专用的快速反馈信道(例如一个或多个CQICH)被分配以提供MMO信道反馈。 In one embodiment, the one or more fast feedback dedicated channel (e.g., one or more CQICH) is allocated to provide a MMO channel feedback such embodiment. 在这个实施例中,一个合适的IE被BS用来向MSS发送分配信息,以识别MSS何时将发送反馈信息。 In this embodiment, a suitable BS IE is used to send allocation information to the MSS, MSS to recognize when to send the feedback information.

[0162] 参考图17,现在将描述这样的一种情况。 [0162] Referring to FIG 17, such a case will now be described. 在第一时间点,如1700指出,BS发送一个反馈资源分配IE,其指出在一个或多个帧上将被分配的总反馈信道数,以便允许MSS有充足容量来发射BS所请求的反馈。 At a first time point, it stated as 1700, a BS transmits resource allocation IEs feedback, which indicates the total number of feedback channels on one or more frames are allocated to allow MSS has sufficient capacity to transmit the feedback requested by the BS. 通过发射一个MSS将怎样发射反馈的指示,反馈资源分配IE还向MSS提供被请求反馈的形式的指示。 By transmitting a transmitting feedback indicating how the MSS, the feedback resource allocation IE also provide an indication of the requested form of feedback through the MSS. 例如取决于天线配置是STTD还是BLAST、平均CQ1、层指数和H、W或V矩阵。 For example, depending on the antenna configuration is STTD or BLAST, average CQ1, and index layer H, W or V matrix. 在一个随后的时间点,如1710指出,MSS用所选择的反馈信道号码向BS发射被请求的反馈。 In a later point in time, it indicated as 1710, the MSS transmits a feedback request to the BS a feedback of the selected channel number. 尽管没有在图17中被特别地示出,然而MSS可以如下所述在多个帧中发射由BS所请求的反馈信息,在这种情况中将有1710的多个实例。 Although not particularly shown in FIG. 17, however, the MSS may transmit feedback information requested by the BS in a plurality of frames, in which case there will be multiple instances of 1710 are as follows.

[0163] 在某些实施例中,BS取决于BS需要来自无线装置的反馈信息的紧急程度来分配上行链路资源。 [0163] In certain embodiments, depending on the BS BS needs urgency feedback information from the wireless device to allocate uplink resources. 如果存在高紧急程度,则BS可以在单帧中指定多个反馈信道以便尽快获得所有的反馈信息。 If the presence of a high degree of urgency, the BS may specify a plurality of feedback channels in order to obtain a single frame as soon as all of the feedback information. 如果存在较低的紧急程度,则BS可以在多帧、相邻帧或具有指定周期的帧中指定一个或多个反馈信道。 If the presence of a low level of urgency, the BS may be a plurality of frames, the adjacent frame or specify a cycle having a specified or more feedback channels.

[0164] 反馈信道可以由图6中的快速反馈信道222来表示。 [0164] feedback channel may be represented by FIG. 6 in the fast feedback channel 222. 如果多于一个的反馈信道被使用,则MSS把反馈信道用作单个上行链路资源来向BSS发送反馈信息。 If more than one feedback channel is used, the feedback channel of the MSS as a single uplink resources to send feedback information to the BSS. 例如,如果反馈信息需要15个比特并且四个4比特反馈信道在单帧中被分配,则MSS在包括四个反馈信道的16比特上的单帧中一起发送15个比特。 For example, if the feedback information is 15 bits and four 4-bit feedback channels are allocated in a single frame, the MSS transmits 15 bits with 16 bits in a single frame on the feedback channel comprises the four. 如果反馈信息需要15个比特并且四个4比特反馈信道在两个相邻帧中被分配,则MSS在第一帧中在包括两个反馈信道的8比特上一起发送15个比特的前8个比特,并且在第二帧中在包括两个反馈信道的8个比特上发送15个比特的剩余7个比特。 If the feedback information needs 15 bits and four 4-bit feedback channel is allocated in the two adjacent frames, the MSS in the first frame 15 transmits the first 8 bits of the two together on the feedback channel comprises an 8-bit bits, and transmits the remaining 15 bits of the seven bits on the two feedback channel comprises 8 bits in the second frame. 当反馈信息的比特数没有填满整数个被分配的反馈信道时,不需要的剩余比特可以或者可以不被用于MSS的随后反馈信息传输。 When the number of bits of feedback information does not fill an integer number of allocated feedback channel, the remaining bits may be unnecessary or may not be used for subsequent transmission of the feedback information of the MSS.

[0165] 上述情况仅仅是反馈信道怎样在一个或多个帧中被分配的例子。 [0165] The case where only a feedback channel example how one or more frames are allocated. 应当理解,任何合理的反馈信道数都可以根据本发明的实施例在任意数量的帧中被分配并且仍然在本发明的范畴内。 It should be appreciated that any reasonable number of feedback channels can be assigned in any number and still frames in accordance with an embodiment of the present invention within the scope of the invention.

[0166] 本发明的实施例现在将关于图18被描述。 [0166] Embodiments of the invention will now be described with respect to FIG. 18. 图18是在MMO-OFDM系统中动态地向无线终端分配至少一个反馈信道的方法流程图。 FIG 18 is a method for dynamically allocating the at least one feedback channel to the wireless terminal in the flowchart of MMO-OFDM system. 在步骤1800,对于一个数据帧,基站向至少一个无线终端发射一个反馈信道资源分配的总数的指示,如所期望的每个相应MSS —个。 In step 1800, data for a frame, a base station transmits feedback channel allocation indicates the total number of resources to the at least one wireless terminal, as desired each respective MSS - a. 如在1810指出的,对于反馈资源分配总数的每个反馈信道资源分配,开始一个循环函数。 For example, for each feedback channel resource allocation of the total feedback resource allocation function 1810 begins a loop indicated. 在步骤1820,基站发射与正在分配反馈信道资源分配的相应无线终端相关联的唯一标识符,并且在步骤1830,在数据帧中发射反馈信道资源的位置。 In step 1820, the unique identifier of the corresponding base station transmitting the radio terminal a resource allocation and feedback channel allocation being associated with, and 1830, transmitting the position feedback channel resources in a data frame at step. 在步骤1840,确定反馈信道当前是否没有被重新分配。 In step 1840, it is determined whether a feedback channel is not currently re-assigned. 如果反馈资源当前没有被重新分配,则在步骤1850,基站发射被分配给相应无线终端的反馈信道总数,该相应无线终端与该标识符相关联,并且在步骤1860,发射一个格式化指数,该格式化指数用于指出与基站和相应无线终端之间的传输信道相关的反馈信息的类型。 If the feedback resource is not currently re-assigned, at step 1850, the total number of the base station transmitting the feedback channel is allocated to the respective wireless terminal, the corresponding wireless terminal is associated with the identifier, and in step 1860, transmits a format index, the formatting index for indicating the type of feedback information related to the transmission channel between the base station and the corresponding wireless terminal.

[0167] 反馈信道IE的一个例子在表8中被示出。 [0167] Examples of a feedback channel IE in Table 8 are shown. 这个IE被BS用来向MSS分配一个或多个快速反馈信道以便MSS提供MIMO反馈。 This IE allocated to the MSS by the BS for one or more fast feedback channels in order to provide a MIMO feedback MSS. 反馈信道分配IE具有:字段,该字段标识多个反馈信道分配或IE将做出的分配;字段,对于每个分配该字段为被分配给MSS的反馈信道设置一个指数值;字段,该字段设置反馈信道将保持多久被分配给MSS ;字段,该字段设置MSS什么时候将在帧级别基础上开始报告反馈;字段,如果反馈信道没有被分配,则该字段设置反馈多长时间将被重复一次;字段,该字段设置多个反馈信道,该反馈信道被分配给由MSS基本CID所标识的MSS ;字段,该字段设置基于"格式化指数"字段所格式化的反馈值的数量,该丨丨格式化指数丨丨字段设置在反馈信道上将被发射的反馈的类型;字段,该字段设置AMC频带指数的长度的指示;和字段,该字段设置CQI值指数的长度的指示并且设置格式化指数。 Feedback channel allocation IE: a field that identifies a plurality of feedback channel allocation or assignment IE to be made; fields, for each assigned to the field to an index value that is assigned to the MSS feedback channel; field, which is provided feedback channel will remain long are assigned to the MSS; field, which is provided MSS when to start reporting the frame level based on the feedback; field, if the feedback channel is not assigned, then the field is set feedback how long it will be repeated; field that a plurality of feedback channel, the feedback channel is allocated to the MSS by the MSS basic CID identified; number of fields, this field is set based on the "format index" field formatted feedback value, the format Shushu feedback type field of index Shushu provided feedback channel to be transmitted; field that indicates the length of the set band AMC index; and a field that indicates the length of the set CQI value index index and format settings. 格式化指数是在从MSS向BS发射反馈信息中将被使用的特殊格式的指示。 Format index is indicated in the special format to be used in the information transmitted from the MSS to the BS feedback.
